I would check that the text is valid and then return the cursor to the cell (and blank it out, if necessary) if the check determined the text to be invalid.

Check out the event:<br />
<br />
DBGrid1_BeforeColUpdate<br />
<br />
In this event , you can validate the new value, track the old value, and cancell the update if your validation requires it !!<br />
<br />
hope this would help!!<br />

Dear Sidneym,<br />
<br />
Sorry if it is so, I am new here and saw no info about getting current value and I think it is not obvious that you have to read the grid text to get it, although it is necessary for the validation of data.<br />
<br />
But if you still feel I should withdraw the answer send an email to gkakas@otenet.gr &nbsp;and I will do it immediatelly.<br />
<br />

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
